Nowadays, every organization wants an extra edge over its competitors. Be it launching a product faster or delivering a higher quality product, they always want to outperform others. To ensure faster got-to-market with a high-quality web application, organizations utilize Selenium test automation in order to automate their test efforts. Enabling them to execute tests faster, with fewer mistakes in a scalable manner. Test automation has certainly made the testing process much faster, but what if I told you that your release can get even faster!
